Is there a way to ping and ldap server? I have seen ldapsearch and ldapwhoami but would appreciate something a bit more like ping. Essentially we have a bip address in front of a selection of LDAP servers and are looking to confirm which one we are connecting to.
Ping is a tool aimed for testing (echo) replies from network hosts using the ICMP protocol. LDAP is a protocol that by default lives on TCP port 389, and does not directly communicate with ICMP.
If you're just looking for a tool to give you a quick "yeah, port is open and available", then you can just do a telnet query for port 389 (LDAP) or port 636 (LDAP SSL) with telnet.
telnet hostip 389
You should see something like this:
root@LINXWII:/home/l0c0b0x# telnet ldapsrvip 389 Trying 10.2.2.101... Connected to mainldapsrv.example.com. Escape character is '^]'.
Lots of people rather use nmap, so you can also do that:
nmap hostip 389
There is also a Microsoft tool called PortQry that will give you a lot of info about a port(s):
PortQry.exe -n hostip -p tcp -e 389
just replace 389 with 636 for LDAP SSL
